Abstract: 277,065. Dawson. Sir A. T., and Buckham, Sir G. T. June 4, 1926. Endless-track vehicles.-A motor vehicle of the kind having endless tracks and road wheels for alternative use, the conversion from an endlesstrack vehicle to a wheeled vehicle being effected by raising and lowering the track-frames, is provided with means whereby the tracks are automatically tightened during the raising of the track frames and are slackened again as the frames are lowered. In the construction shown in Fig. 4. in which the track frames are connected to the chassis A by pivoted arms or levers E the forward arm is provided with a projection E<1> connected by a link E<2> with a block E<3> carrying the idler wheel D<1> of the endless track. Thus as the links E are rotated so as to raise the tracks to the position shown in broken lines the blocks E<3> are moved to the right .and the tracks are tightened. The links E<2> may be made adjustable to allow the normal tensioning of the tracks to be effected, or the axes of the idler wheels D' may be adjustably mounted in the blocks E<3> for this purpose. Modifications are described in which (1) eccentrics on the links or levers E are connected by links to the sliding blocks E<3>, (2) stops are provided on the chassis in such positions that as the tracks are raised their upper portions contact with the stops and so the tracks are tightened, and (3) jockey wheels for the upper portions of the tracks are moved upwards relatively to the track frames during the upward movements of the latter. Specifications 277,062, 277,064 and 277,066 are referred to.

Abstract: 1,085,067. Radiant tubes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 29, 1966 [April 2, 1965], No. 14181/65. Addition to 1,067,511. Heading F4B. In a fluent fuel fired radiant tube, fuel is fed via a central passage 9, combustion air is fed to a passage 13 through an annular passage 11 surrounding the end of the radiant tube, and combustion products escape through a passage 15. Radial internal and external fins on a heat exchanger 31 separating passages 13 and 15 improve the heating of the combustion air by the combustion products, and the inflowing air in the jacket 11 prevents heat loss to the surroundings. The combustion air in passage 13 flows in the opposite direction to the combustion products in passage 15. In a hairpin tube, the fuel feed tube is omitted and the heated air and fuel are fed to the other end of the tube from that accommodating the heat exchanger. The heated air may be used in another similar radiant tube.

Title: Thread cutting mechanism for sewing machines
IPC: D05B65/00
Filed: 1920-06-02
Abstract: 144,291. Singer Manufacturing Co., (Assignees of Wood, A. R.). Oct. 13, 1915, [Convention date]. Button-hole sewing-machines; thread-cutters and end-holders.-In a machine arranged to cut and hold the stitching-thread and the strengthening-cord at the completion of a button-hole, devices are provided whereby the thread-cutter and end-holder may be held out of action at the completion of one stitching operation when it is desired to stitch over the button-hole a second time. The cutting and end-holding levers are pivoted between the recessed underside of the work-clamp 16 and a resilient plate with a sharpened edge. The upper end-holding lever has a wide throat by which the stitching-thread and the strengthening- cord are ,gathered together before being locked between the lever and the underside of the workclamp. The levers are withdrawn against the resistance of a spring 70 by means of a push rod 66 and a stop which engages the end thereof. The push rod is held in withdrawn position by a latch lever 125 which falls into engagement with a shoulder upon the rod. When the machine is stopped the latch is withdrawn by means of the parts 131, 111, 127, and the cutting and endholding operations are then occasioned 'by the spring 70. The push-rod is brought into engagement with the stop, both by the movement of the work-clamp and by an opposite movement of the stop, which for this purpose is carried upon a sliding block 83; the sliding block being moved forward by means of a pin 90 rotating with the cam-shaft 28 and engaging with a face 89<x> on the block. In order to make the stop ineffectual when it is desired to stitch over a button-hole a second time, the stop is provided in the form of a disk 85 with upstanding stop portions 88. The disk carries a ratchet-wheel having twice as many teeth as there are stops 88, and engages with a stationary pawl 105 on each return reciprocation of the sliding block 83. Accordingly, only on alternate outward reciprocation of the block 83 is there a stop 88 in line with the push-rod 66. The other reciprocations do not cause the actuation of the push-rod and the withdrawal of the threadcutter, and, at the corresponding occasions when the machine is stopped, the thread-cutter and endholder are not actuated. The lever 106 carrying the pawl 105 can be moved into an inoperative position when it is held by a spring clip 113. The pin 90 can be placed in any one of three holes 97 to vary the time of the withdrawal of the threadcutter and end-holder.
